I just acquired this UMC-based SBC 486 motherboard, from eBay:
And here is the back:
It came among with this attached VGA card:
The only label on the board is INS-UMB486DX/LAN/CACHE. I’m guessing that “INS” is either the manufacturer, or a shortened version of “industrial single board computer.” Neither the LAN nor the cache options seem to be populated, on the board. The board has jumper settings for CPU speeds between 20 and 80 MHz.
Any suggestions are welcome. I can figure out most of the headers, but some are mysterious.
